Ceramic Support Balls

Made of yttria stabilized zirconium oxide are characterized by an extremely high wear resistance. This property is based on the use of ultrafine crystalline and high-purity raw materials in the manufacturing process and on the constant chemical composition.

Product Details

Product Introduction:

Made of yttria stabilized zirconium oxide is characterized by an extremely high wear resistance. This property is based on the use of ultrafine crystalline and high-purity raw materials in the manufacturing process and on the constant chemical composition. The very good sphericity and the dense, polished surface of the beads also contribute to this wear resistance and thus to the long lifetime circle.
